Comparison of EDTA and SDS as potential surface impregnation agents for lead adsorption by activated carbon
Source abstract
Abstract
Abstract Ethylene diamine tetraacetic acid (EDTA) and sodium dodecyl sulfate (SDS) were employed to impregnate activated carbons for the purpose of lead removal. The mechanisms of surface impregnation and lead adsorption method of chemical regeneration were investigated. Results showed that the highest impregnation of EDTA and SDS on activated carbon was 0.33 and 0.96 mmol/g, respectively. Adsorption capacities for lead of EDTA and SDS impregnated activated carbons reached 0.29 and 0.24 mmol/g. Rapid small scale column tests of adsorption and regeneration were conducted. Lead adsorption was greatly enhanced by EDTA impregnation. In addition, EDTA impregnated adsorbent was able to be successful regenerated by HNO 3 and thus reused.
